Hydrogen Detector System
 (included)
|
-
One Honeywell UL Approved Sensepoint Gas Detector is Integrated into the system.
-
Working Temperature Range: 40ºF to +149ºF (-40ºC to +65ºC)
-
Alarm Point: H2 Limited Explosive Line 20% (20% LEL). Once detecting H2 gas beyond the point, it will shut off the inlet valve to the H2 and heating elements automatically.
|
|
Gas-outlet Flowmeter
|
-
One 0 -1000 ml/min floating meter is installed on gas-outlet end for adjusting gas flow rate.
-
1/4" Dia stainless steel tube is installed for burning hydrogen gas during gas flowing.
-
One long lighter is included in the standard package for igniting hydrogen gas manually.
-
Solenoid value automatically shuts down the gas inlet and heating elements in case of system failure.

Electromagnet Sample Release Flange & Quenching
|
- Full automatic electromagnet sample release flange
- Hinged plate hooks the cable, which pulls the sample.
- Hinged plate drops when the electromagnet powers off. The sample and the cable fall into the quenching tank.
- Rings are available for hanging the tube block with cables.
- Bottom flange is connected with a 4" gate valve ( manual operated ) via CF-100 adaptor
- The gate valve is connected with a quenching media container in size 400 x400 x 200 H ( mm )
- Caution: You must use ice water or cooled oil as a quenching agent if quenching under vacuum.

Gas Purification and Circulation
(Optional)
|
- EQ-RMP-1 is an automatic recirculating moisture and oxygen purification system, which can provide an environment with moisture and oxygen concentration lower than 1 ppm for MTI's furnaces and gloveboxes.
- Two-columns of Molecular sieves are Built-in in the system. One is for removing oxygen and another is for removing moisture up to < 1 PPM
- The automatic pressure control system is built in to keep the pressure at a constant level
- 6" color PLC touch panel is included which can set and display the humidity and pressure level
- Oxygen sensors and moisture sensors are included.
|
Hermetic Quenching Tank
(Optional) |
- Hermetic quenching tank is optional for air-sensitive materials, which enables the entire quenching process under atmosphere control
- Please contact MTI for further inquires.
